Provided is a multilayer adhesive tape having excellent step coverage and reworkability. The multilayer adhesive tape sequentially includes: a first outer adhesive layer; an intermediate adhesive layer; and a second outer adhesive layer, in which the intermediate adhesive layer includes an intermediate adhesive polymer including: a polymerization unit of an alkyl group-containing (meth)acrylate monomer; a polymerization unit of a carboxyl group-containing monomer; and a polymerization unit of an acrylamide-based monomer.

Multilayer adhesive tape

A multilayer adhesive tape in which an interface separation between layers does not occur even at in extremely low temperature atmosphere is provided. The multilayer adhesive tape sequentially includes: a first outer adhesive layer; an intermediate adhesive layer; and a second outer adhesive layer, in which attaching force among the first outer adhesive layer, the intermediate adhesive layer, and the second outer adhesive layer is maintained after the multilayer adhesive tape is treated in liquefied nitrogen for 15 seconds.

Multi-layer adhesive tape

A method for manufacturing a low molecular weight acrylic resin, and more particularly, to a method for manufacturing a low molecular weight acrylic resin having a high conversion rate and a low poly dispersion index includes maintaining the temperature of a reacting part with a screw stirrer at a specific temperature during a continuous polymerization of a solvent-free acrylic composition in a continuous flow reactor having the reacting part.

Method for manufacturing low molecular weight acrylic resin

The present application relates to a photocurable solventless pressure-sensitive adhesive composition, a pressure-sensitive adhesive polarizing plate and a display device. According to the present application, a pressure-sensitive adhesive composition, a polarizing plate and a liquid crystal device, which have excellent durability and antistatic abilities, can be provided.

Pressure-sensitive adhesive composition, polarizing plate, and optical member

A multilayer adhesive film is provided including: a first outer adhesive layer; a second outer adhesive layer; and an intermediate adhesive layer disposed between the first outer adhesive layer and the second outer adhesive layer. The multilayer adhesive film has both high step absorbency and excellent reworkability.

Multilayer adhesive film

A multilayer adhesive tape exhibiting high step coverage and having both high reworkability and excellent punchability is provided. The multilayer adhesive tape sequentially includes: a first outer adhesive layer; an intermediate adhesive layer; and a second outer adhesive layer, in which a glass transition temperature of the intermediate adhesive layer is &#x2212;40&#xb0; C. or more and 0&#xb0; C. or less, a glass transition temperature of each of the first outer adhesive layer and the second outer adhesive layer is &#x2212;60&#xb0; C. or more and &#x2212;20&#xb0; C. or less, and a difference in glass transition temperature between each of the first outer adhesive layer and the second outer adhesive layer and the intermediate adhesive layer is 5&#xb0; C. or more and 25&#xb0; C. or less.
